Priority configuration

Category: Hardware
Product Number: LTC4418


I would like to develop a circuit using the LTC4418/4421 that includes 2 sources, when there is a priority between primary and secondary. If the primary enters the UV, I would like to switch to the secondary and not go back, even if the primary passed the UV threshold and is considered normal. Does one of this components allow this? Perhaps a two-component CAS would allow this? I would appreciate recommendations
